Re: looking for relatives

I am searching for any information on a Cha. (charles?) P. Mausbach age 36 in the l880 census of Harris Co., Tx. He was born in Prussia. His wife was Alexandria Liebman age 34 b. Prussia. They had the following children: Constance 9 born Tx, Alfred 7 b. Tx, Hager 4 b. Tx. and Margaret Gretchen 3 b. Tx. Helisted hisoccupation as collector. I have many questions about the Mansbach name. Is this name associated with any particular part of Germany? Does anyone have any suggestions on research on line in Germany that might help me? Thank you. Barbara
